SPECIFICATION forming part of Letters Patent No. 541,41 5, dated June18, 1895.

Application filed November 13, 1894. S rial No, 528,690. (No model.)

T to whom it may concern:

Be it known that 1, FREDERICK A. BAIER, of the city of St. Louis, in theState of Missouri, have invented a certain new and useful Improvement inStreet-Cars, of which the following is a full, clear, and exactdescription, reference being bad to the accompanying drawings, formingpart of this specification.

My invention relates to an improved con- ;o struction for street cars,the object being to provide strength and firmness to the frame work, andto provide against moisture getting between the posts and the sills uponwhich they rest.

My invention consists in featuresof novelty hereinafter fully describedand pointed out in the claims. 7

Figure I is a side elevation of my improved car, part broken away. Fig.II is an enlarged detail section of one of the truss-rods and one endsof the sill.

of the posts, showing one of the truss-rod brackets in edge view. Fig.III is amenlarged detail top view of one corner of the car, showing thecurvature of the truss over the Fig. IV is a detail side view. Fig. V isa section taken on line V V, Fig. III. Fig. VI is a perspective view ofone end of one of the side sills. Fig. VII is a perspective view of oneend of one of the end sills.

Fig. VIII is a perspective view on a smaller scale, showing the sillsjointed together.

Referring to the drawings, 1 represents one of the side sills of thecar; 2, the end sills; 3, the floor; 4, one of the truss-rods, and 5 the5 main posts extending along the sides of the car and resting on theside sills. Each end of each side sill is formed with a tenon 6 thatfits in a mortise 7 in the end sill, and each end of each side sill hasa tongue 8 that is received by a shallow notch 9 in the end sill,

the tongue being somewhat thicker than the notch is deep, so that theupper face of the side sill is slightly 'higher than the upper face ofthe end sill and the surface of' the floor,

5 see Fig. VIII, and thus moisture is prevented from passing off thefloor onto the upper surface of the side sills and rotting the lowerends of the posts where they rest on the side sills.

they will lie flush with the upper surface of the end sills, as shown inV and VIII.

The end sills are perforated at points adjacent to the sills so as toprovide diagonally positioned holes 11 to receive the ends of the trussrods. The perforations or holes are formed inside of the mortises 7 sothat the truss rods do not pass through the side sills but on the insideof them, as shown in Fig. I, so that while the side sills are supportedand strengthened by the truss rods they are not weakened by the rodspassing through them. The rods are provided with washers and nuts 12fitting against the lower outside corners of the end sills.

The truss rods extend, in elevation, to a point well up and horizontallyunder the car windows, as shown in Fig. I, and they extend along insideof the main posts 5 to which they are made fast by straps 13. See Fig.II. By thus extending the rods to a high elevation and making them fastto the posts, the sills aremuch better supported than with the ordinarylow truss rods, and the sills and posts are bound and held together in avery firm and rigid manner.

As shown in Fig. IIIthe truss rods are curved outwardly after risingover theside sills so as to come against the posts, andthe result ofthis is that the rods exert an inward pull on the posts, preventing thelatter from being strained outwardly when the car is in use.

I claim as my invention-- 1. A car comprising a side sill, the end sillssecured to the side sill, the main posts sup ported on the sills, thetruss-rod having its ends extending diagonally through the end sillsinside of the side sill, curvedoutwardly over the side sill, andextending horizontally under the windows, means for securing thetruss-rod to the main posts, and means for securing the ends of thetruss-rod to the end sills; substantially as described.

2. A car comprising the side sill having a tongue, and a tenon at eachend, the end sills having a shallow notch, a diagonal hole, and V amortise, the main posts supported ,on the side sill, the truss-rodhaving its ends extending through the diagonal holes of the end sillsinside of the side sill, curved outwardly over the side sill andextending horizontally under the windows, straps for securing thetruss-rod to the main posts, and washers and nuts for securing the endsof the truss-rod to the outer lower corners of the end sills;substantially as described.
